ATIQRNEAYS United States Patent 3,315,593 TYING MACHINE Wright A.Scoville, P.0. Box 2429, White City, Oreg. 97501 Filed Dec. 3, 1965,Ser. No. 511,466 7 Claims. (Cl. 100-27) This invention relates toapparatus for securing an article or articles by wrapping a cord, tapeor the like thereabout and securing the same in encircling relationabout such article or articles.

The word tying is used in the broad sense inasmuch as a cord or the likeis not knotted or formed with a knot. In the embodiment illustratedherein, the ends of the encircling cord are secured by staples, andWhile the word cord will be used to identify the tying medium, it is tobe understood that any similar tying medium such as tape, etc., may beused.

One of the objects of the invention is the provision of apparatus forsecuring a'cord tightly about a package, bundle of articles, or thelike.

Another object of the invention is the provision of apparatus forsecuring a cord or the like tightly about a package or bundle ofarticles by stapling the ends of a leading section of a continuous cordabout the package or articles after the apparatus has tightly drawn suchsection about the packageor articles and then severing such leadingsection from the remainder and cutting it from the latter, and thensetting the machine for subsequent tying operations. I

Another object of the invention is the provision of improved apparatusfor securing succeeding sections of a pair of continuous cords about theopposite end portions of horizontally elongated bundles of similarlyelongated elements, by encircling each of successively presented bundleswith said sections, under tension, and securing the ends of each suchsections to each other and to the ends of the bundles, and thereafterautomatically severing the sections so secured from the remainders ofthe continuous cords, and then repeating the cycle including thepresentation of the bundles.

Other objects and advantages will appear in the description and in thedrawings.

FIG. 12 is a simplified view showing an installation for tying orsecuring together the ends of bundles of elongated articles, such asflooring.

Referring to FIG. 1, an article to be tied, which may be a container,package or a bundle of elements, is indicated in dot-dash line and isgenerally designated 1. This article is supported on the upper run of anendless conveyor, generally designated 2, or any other suitable support.The conveyor, or support, is in a position spaced from one side of theframe 3 of-the tying machine, and it is adapted to support the article 1thereon in a position projecting from said support in a direction towardsaid frame a sufficient distance to enable a horizontally disposed arm 4on the tying machine to complete 360 degree revolutions, and more,around the portion of the article that projects from said support.

Suitable bearings 5 on frame 3 (FIG. 2) rotatably support a horizontalshaft 6, in a position extending at a right angle to the length ofconveyor 2 with one end projecting from a side of frame 5 adjacent tosaid conveyor. Said projecting end of shaft 6 has a radially outwardlyprojecting arm 7 projecting therefrom; and the aforesaid arm 4, whichmay be called a tying arm, is rigid with and projects horizontally fromthe outer end of arm 7 in a direction away from frame 3.

From the foregoing, it is seen that the arm 4 will .revolve in anannular path 9 (FIGS. 1, 11) upon rotation of shaft 6, and the latter isconnected, through suitable reducing gears, with a mot-or 10 (FIG. 2)through sprocket wheels 13, 14 that, in turn, are connected by asprocket chain 15.

The upper run of conveyor 2 is supported on a rigid support 16 (FIG. 1)at the point adjacent to frame 3 where the article 1 is supported fortying, and said conveyor supports article 1 in a position in which thearm 4 will revolve completely about the projecting end of said article(FIGS. 1, 11).

FIG. 12 shows the article 1 as comprising a bundle of flooring ofuniform length with the flooring arranged to provide a square crosssectional container (FIG. 1). The conveyor in FIG. 12 comprises a pairof endless chains 17 in horizontally spaced side by side relationextending at their opposite ends over sprocket wheels 18 that are onparallel shafts 19. A sprocket wheel 20 secured on one of the shafts 19is connected by a sprocket chain 23 with a sprocket wheel 24 that, inturn, is driven through reducing gears by a motor-brake 25. Chains 17are provided with lugs 26 (FIG. 1) that project upwardly from theupperruns of the conveyors for spacing the bundles along the chain, andthe circuit for motor 25 includes a control box 27 (FIG. 3) in which theconveyors are timed for intermittent movement with the movementsof thetying machine.

The bundles l'positioned horizontally extending across the conveyorchains by lugs 26, have their ends projecting oppositely outwardly fromthe opposite sides of the pair of chains and a pair sponding to themachine of FIG. 1 except the left-hand tying machine is complementary tothe right-hand machine in operation, are at opposite sides of theconveyor with their forward sides facing each other so that the arms 4,when actuated, will similarly revolve about the projecting ends of thebundles 1 upon each bundle being of the tying machines, each corre-.

' suspended a plate 34 from a As viewed in FIG. 2, the frame 3 includesa vertically extending post 28. Adjustably secured on said post forvertical movement to different levels is a bracket 29 extendingangularly upwardly and forwardly relative to post 28, the forward sideof the frame is the side at which bundle 1 is positioned. a

7 Set screws 30 secure a sleeve 31 on the lower end of bracket arm 29 atthe desired level on post 28 for supporting the elements carried by thebracket at the desired level.

The bracket arm 29 is relatively wide and has a pair of ears 33 (FIG. 1)at the upper end between which is horizontal pin or pivot 35 that.extends between said ears. Connected to the rear side of plate 34 by apivot 36 (FIG. 6) is a piston rod 37 that projects from an air cylinder38 (FIG. 2) which cylinder, in turn, is pivotally connected at its endopposite to said piston rod with the bracket 29. By this arrangement,one actuation of the air cylinder may swing the plate 34 and anyelements supported thereon forwardly to dot-dash line position 39 (FIG.2) and 'an opposite actuation will return the'plate to verticallysuspended full line position.

A vertically elongated plate-like arm 40 is pivotally suspended at itsupper end portion to plate 34 at the forcentral longitudinal axis 7 rearside of plate 40, and a nylon brake-plate 66 extends a I transversely ofplate 40 across theunder surface of poractuation of the cylinder willresult in the clamping jaw;

47 being in clamping engagement with lug 46.

The end of arm 48 that is opposite to pivot 49 is formed with a downwardprojection 55 (FIG. 7) that is formed with a through aperture 56, thewalls of which are preferably outwardly flared at its ends for passageof a tying cord 57 therethrough and any continuous source thereof,.suchas a roll 58 (FIG. 11) carried by a support 59 that, in turn, may besecured to frame 3 and which roll may include any suitable conventionalbrake means (not shown) to prevent over-running when cord is drawntherefrom.

At the lower edge of the plate '40 opposite to projection 55, said plateis formed with a generally inverted L-shaped portion (FIG. 7) thatprojects forwardly of the plate with the leg with aperture 56, and is ofthe same shape.

The portion 63 may continue transversely across the lower edge of plate40 to project at 65 (FIG. 8 to the tions- 63 and. 65, said undersurfacebeing at about thelevel of aperture '64. A spring 67 (FIG. 8) aboveportion 65 and around 'an upstanding bolt 68, that is threaded intoplate 66 and that freely extends through an opening V in portion 65,reacts between the head of the bolt at its 65, and portion 65 yieldablyholding the brake plate'66 against the undersurface of upper end aboveportioni projection 63 when no'cord is in place.

ward side of the latter by a pivot 43 (FIG. 1) for swinging inapproximately the same vertical plane as the plane a in which path 9 ofarm 4 and conveyor 2 are disposed,

andawhich plane is normal to the direction in which plate 34 is adaptedto swing about pin 35.

Plate 34 is formed with a forwardly projecting stop 'in the form of alug44 along the edge thereof that faces away from armr4.- A spring 45 isconnected at its opposite ends to arm and plate 34 for yieldably holdingarm 40 against a lug 44 (FIG; 1) on plate 34, whileithe lower end ofsaid arm is adapted to swing clockwise, as viewed in FIG 1, against theresistance of said spring.

The lower edge of arm 40 is' relatively wide in the plane in which the Vpivot'43, :and spaced between theends 'of said edge and lower end isadapted to swing about integral'with arm 40, is a forwardly projectinggenerally I horizontally elongated stationary lug'46 (FIG. 7) that hasan'upwardly facing convexly curved upper surface,

which lug extends longitudinally of said lower edge. 1 Above said lug isa movable clamping jaw 47 that has a lower generally horizontallyelongated surface that is concave'and complementarily surface of lug46,7

a The outer end of arrn 4 beyond pivot 73 extendskup I wardly andoutwardly to provide a stationary, clamping jaw 7 4 toward which theelement 71 is adapted to: swing to engage a cord clamping relationbetween element 71 and jaw 74.

Supported on frame 3 substantially above the circularpath 9'of the outerend of arm 4 is a stapler assembly generally designated 82 (FIG. 1).The'stapler 83 .of'the stapler assembly is conventional, and 'itincludes a magwhich cord may be drawn from 60 of said portion projectingdownwardly, and with the arm 63 of said portion extending toward theclamping jaw 47. The depending leg 60 is formed with. an aperture 64that is approximately in alignment 4 carn'es a cord clamping and cuttingmechanism generally designated 69 in the form of a cutting blade 70 anda clamping element 71 (FIGS; I 1 9, 10) that are pivotally supported onarm 4 at'one ofQ and release the hammer for driving the staples uponeach downward movement of the head 85 into engagement with the material1 to receive the staples, and to cock the stapler head upon each upwardmovement of the head.

The stapler 83 is secured to and below a horizontal plate 86 that, inturn, has a pair of spaced vertical bolts 87 (FIG. 4) secured theretoand projecting upwardly therefrom.

Spaced above plate 86 is an upper plate 88 that, in turn, is formed withdownwardly projecting bosses 89 that have vertical open ended borestherethrough through which the upper ends of bolts 87 project. Nuts 90on the upper ends of said bolts function as stops for upward movement ofthe plate 88. Helical springs 93, through which bolts 87 extend, reactbetween plate 86 and bosses '89 to yieldably hold them spaced apart.

Above the plate 88 is an overhead arm 94 that is rigidly secured at oneend to the upper end of frame 3, and this arm projects outwardly offrame 3 so that the outer end portion of arm 94 is over path 9. Avertical air cylinder 95 is secured at its lower end to said arm withits piston rod 96 (FIG. 4.) freely extending through an opening in arm94 and the downwardly projecting end of said rod 96 is secured to plate88.

A vertical guide rod 97 (FIG. 1) spaced from rod 96 is secured at itslower end rto plate 88 (FIG. 4) and also extends through an opening inarm 94 and is reciproca-ble through a vertically extending boss\98(FIG. 1) rigid with arm 94.

Upon downward movement of piston rod 96 under the influence ofcompressed air in cylinder 95, the stapler will be moved down to effecta stapling operation, and the provision of springs 93 compensates forvariation in the vertical thickness of bundles and insures a firmcontact of the stapler with the material 1. Also the springs have acushioning effect, and enable the relative movement between the plates86, 88 for actuation of the microswitch 99 (FIG. 1) on plate 88, whichactuates the solenoid valve in the air line to cylinder 95 for returningthe air cylinder and stapler to its original elevated position.

From the foregoing description, it is seen that there are several aircylinders, namely; and in the order in which they are mentioned, thecylinder 38 that is connected with the plate 34 for swinging plate 34and arm 40 between the full line and dot-dash line position 39 (FIG. 2);the :air cylinder 50 that actuates the clamp 47, that in turn, is on arm40; the air cylinder 80 on arm 4 that actuates the cord clamping andcord cutting means on said arm, and the air cy der 95 for the stapler.

These are all double acting air cylinders, except the cylinder 80, andeach has conventional air pressure lines connecting each withconventional solenoid valves that, in turn, are controlled in thedesired sequence by conventional adjustable rotating cam limit switchesin a control box 27. The air cylinder 80 is single acting and iscontrolled by a cam-actuated limit switch in box 27, but the air lineleading to the air cylinder 80 comprises a duct 100 (FIG. 2) extendingfrom the source of compressed air to cylinder '80 and the piston rod inthis instance is spring returned after actuation for cutting andclamping the cord. Said source is indicated at 101.

The motor for actuating arm 4 and the conveyor 2 are of the conventionalty each having an automatically actuated brake to prevent over-runningwhen the circuit thereto is broken, and in FIG. 12 a stationarymicroswitch 102 in a circuit to the control box 27 may be actuated byengagement with load 1 to stop the conveyor at the tying station andupon the tying' cycle being concluded, the current to the motor 25 willbe re-established for moving the next bundle to the tying station.

A brief explanation of a cycle of operation is as follows, referring toFIG. 11.

The cord clamping and cutting mechanism 69 on the outer end of arm 4 isshown at A in a position approximately at 11 oclock, viewing theapparatus toward the forward side, as seen in FIG, 1, and the cylinder80 may be actuated by a manually actuatable switch in the electricalcurrent to grip the cord when the latter is in position A. This ismerely to start the operation, since subsequent operations and cyclesare automatic. The circuit for the cycling operation is then closed, andthe undle 1 being in a position substantially coaxial with the axis ofshaft 6, the arm 4 will be revolved counterclockwise through positionsB, C, D, B. At position C, it will be seen that the cord clampingmechanism 69 would engage the dot-dash line position 105 of the cord 57,were it not moved to a position to one side of the dot-dash position,and just before the mechanism 69 reaches the cord, the air cylinder 38that is connected with plate 34 will swing the latter to position 39(FIG.

2) to permit the clamping mechanism 69 to pass the cord at position 105,and then the plate 34 and the clamps 46, 47 will be returned to theirnormal position D (FIG. 11).

While the clamping mechanism 69 is moving counterclockwise from positionA to D in the wrapping step, the clamp 48 on plate 40 is inoperative,and the plate 40 will be held in the full line position under thetension of spring 45. The friction of the friction block 6 is notsul'ficient to overcome the tension of spring 45, but it does hold thecord straight.

When the cord clamping mechanism 69 reaches approximately the positionE, which is approximately a 12 oclock position, the air cylinder 50 onplate 40 is actuated to cause clamp 47 to firmly grip the cord, andthereafter during movement of the clamping mechanism 69 through positionA to position -B will place a substantial tension on the cord to tightenit about the bundle 1 since the plate 40 will be swung clockwise to movethe clamping elements 46, 47 (now in cord clamping position X toposition Y [FIG. 11]), and the plate 40 will swing against theresistance of spring 45.

When the cord clamping mechanism 69 reaches position B, the air cylinder95 of the stapler is actuated to staple the lapping side-by-side endportions of the section of the cord that is tightly wrapped about thetop of the bundle and to each other, after which the cord at themechanism 69 is released through release of air pressure in cylinder 80.

The clamping and cutting mechanism, in open position, then moves againto and through position C but without the cord. This time the aircylinder 38 is not actuated to swing plate 40, hence the cord will beengaged by the clamping mechanism and/the latter will be actuatedthrough actuation of cylinder to both sever the portion of the cordbetween the cutting mechanism and the staple, and to grip the end of thecord that extends to the clamp, of the tensioning device that includesplate 40, the clamping action taking place before the cutting of thecord.

The clamp 47 on plate 40 may be released after the cord is cut atposition B to release the plate 40 and then the conveyor may be actuatedto bring the next bundle to the desired position for tying while theclamping. mechanism 69 moves to position A and through the cycle asdescribed.
